The ViewCube ® is an on-screen 3D navigation element that: 

  • provides feedback about the current camera view in relation to the 3D scene. 
  • lets you quickly and easily switch between scene views. 

The ViewCube appears in the upper-right corner of the Meshmixer viewport as a cube with individual faces labelled to indicate the camera view in relation to the scene. 

The default camera view in Meshmixer is the Perspective view, a standard three-quarter view with a perspective projection. As the camera view is adjusted, the ViewCube updates to reflect the camera’s current position and orientation in relation to the scene. 

Clicking on a particular face of the cube automatically adjusts the camera’s view so it matches that face. The viewing camera animates in real-time during the transition between views so you can see how the orientation of the camera changes in relation to the scene. Clicking on the edges or corners of the ViewCube adjusts the camera view to positions that are in-between the face views. Clicking on the Home icon resets the camera’s position to the default perspective view.

The ViewCube can also be dragged and snapped to different positions other than the fixed views providing many other viewing options. The ViewCube outlines are drawn with a dashed line style when this occurs. 

The ViewCube is on by default -- you can turn it off in the Preferences window. 

Using the ViewCube

When you position the mouse pointer over the ViewCube, regions of the cube appear highlighted. The highlighted areas of the cube (faces, corners, and edges) indicate the view that will be selected when you click your mouse. 

To change the scene view using the ViewCube

  1. Position your mouse pointer on the ViewCube so that the desired region is highlighted. 
  2. Left-click on the highlighted region of the ViewCube. 

    The scene view changes to match the point of view that corresponds to the region of the ViewCube you selected.

To reset the scene view using the ViewCube

  1. Click the Home button above the ViewCube. 

    The camera returns to its default position. That is, clicking the Home button in the orthographic views (Front, Top, and Side) resets the views to their default camera positions. Clicking the Home button in the Perspective view resets the camera’s position to a three-quarter view with a perspective projection. 

When viewing the scene in an orthographic view, four small arrows surrounding the ViewCube are used to rotate the camera to an adjacent orthographic view.

To view an adjacent orthographic view using the ViewCube

  1. In an orthographic view, click on any of the four arrows that appear around the ViewCube. These arrows represent the views adjacent to the current orthographic view. 

    The orthographic view changes to match the adjacent orthographic view you selected on the ViewCube.

When viewing the scene in an orthographic view, two curved arrows appear in an arc shape adjacent to the ViewCube to control clockwise and counter-clockwise rotation (roll) of the scene view. 

To roll an orthographic view using the ViewCube

  1. In the desired orthographic view, click on a curved roll arrow to roll the view in either a clockwise or counter-clockwise direction. 

To tumble the scene view using the ViewCube

  1. Click-drag on the ViewCube in any direction to tumble the view.  

Context Menu

Clicking on the down arrow near the ViewCube will bring up a context menu. You can use this to change ViewCube properties and to change some default views.

Home: go to the Home view.

Perspective/Orthographic: toggle between Perspective and Orthographic projection

Set Current View as Home/Front: set the current camera position and orientation as the Home view or the Front view.

Reset Front: return the Front view to default.

Properties

Show the ViewCube: draw the ViewCube in the Meshmixer viewport.

On-screen position: which viewport corner the ViewCube is drawn in.

ViewCube size: choose from preset sizes, or choose Automatic to have the ViewCube change size based on the size of the Meshmixer main window.

Inactive opacity: when your mouse cursor is not near the ViewCube, you can have it become semi-transparent to avoid interfering with your scene.

Keep the scene upright: Prevents you from flipping the model upside down as you manipulate the view with the ViewCube.

Snap to closest view: while dragging the ViewCube to change the camera orientation, you can have the camera "snap" to the preset views corresponding to the faces, edges, and corners of the cube.

Fit-to-view on view change: if this property is checked, the camera will dolly in and out when the view changes so that the scene will fit in the viewport. If unchecked, the camera will rotate but maintain the same distance from the scene as the views change.

Use animated transitions: choose whether the camera should smoothly animate when a new view is selected, or jump immediately to the new view.

Show the compass: the compass provides another method for changing the views. Rather than Front, Left, Right, and Back views, the compass has North, East, South, and West directions. Click and drag on the compass to spin the model while keeping it locked to the horizontal plane, or click one of the cardinal directions to move to that view.

Angle of north: specify a relative angle between the Front view and South view. 

Restore Defaults: return all Viewcube properties to the defaults that come with Meshmixer.
